- 4 teaspoons baking powder
- 3/4 cup (1 1/2sticks) chilled unsalted butter, cut into 1/4-inch pieces
Preheat oven to 425°F. Whisk flour, sugar, baking powder, salt and baking soda in large bowl to blend. Using fingertips, rub 3/4 cup chilled butter into dry ingredients until mixture resembles coarse meal. Add buttermilk and stir until evenly moistened. Using 1/4 cup dough for each biscuit, drop biscuits onto baking sheet, spacing 2 inches apart. Bake until biscuits are golden brown on top, about 15 minutes. Cool slightly. Serve warm.
